风冷控制柜是配套大型电力变压器及特种变压器的冷却控制装置.它能根据变压器的温度和负荷自动投入或退出冷却回路.我公司研发的风冷控制柜动力电源采用双电源供电,由选择开关选择其中一路作为工作电源回路,另一路作为备用电源回路.当工作电源回路出现断电、缺相、过载、短路、欠压等故障时,送出电源故障信号,备用电源回路自动投入,保证冷却风扇或油泵正常运行.主变风冷控制柜具有密封可靠、补偿元件强度高、无老化、与变压器等寿命、无需维护等特点,能有效提高油质保护的可靠性和减少定期维护工作量.这种NS-BFK风冷控制柜是用不锈钢薄板经特殊工艺胀压成形的波纹管,代替胶囊和橡胶隔膜,从而有效防止了因胶囊或橡胶隔膜的各种缺陷引发的故障,提高了电网供电的可靠性,降低了电网维护的费用
Air-cooled control cabinet is a cooling control device supporting large power transformers and special transformers. It can automatically put into or withdraw from the cooling circuit according to the temperature and load of transformers. The power supply of air-cooled control cabinet developed by our company is powered by dual power supply. One of the power supply circuits is chosen by the selection switch, and the other is used as the working power supply circuit. Standby power supply circuit. When the power supply circuit breaks down, lacks phase, overloads, short circuit, undervoltage and other faults occur, the power supply fault signal is sent out, and the standby power supply circuit is automatically put into operation to ensure the normal operation of cooling fan or oil pump. The main transformer air-cooled control cabinet has reliable sealing, high strength of compensating elements, no aging, and transformer life, etc. The NS-BFK air-cooled control cabinet is a corrugated tube formed by special bulging process of stainless steel sheet instead of capsule and rubber diaphragm, which can effectively prevent the faults caused by various defects of capsule or rubber diaphragm and improve the power grid. Reliability of power supply reduces the cost of power grid maintenance
